The endocrine system
consists of glands or parts of glands whose secretions (called hormones)
are distributed in the human body by means of the bloodstream.
The major organs of the endocrine system are the hypothalamus, the pituitary
gland, the thyroid gland, the parathyroid glands, the islets of the pancreas,
the adrenal glands, the testes, and the ovaries. During pregnancy, the
placenta also acts as an endocrine gland in addition to its other functions.
